A Fast Solution Method to Economic Dispatch Type Problem

A Fast Solution Method to Economic Dispatch Type Problem

Economic dispatch (ED) aims to minimize the generation cost subject to power balance constraints. It is extensively used in power system operation and planning. ED problem as well as other problems with the same formulation are named as ED-type problems in this letter and a fast solution method is p...
